1 Avoid sweets and sugars. They aggravate the dumping syndrome. 2  Avoid very hot or cold foods or liquids, which may increase symptoms in some patients.  Stomach surgery is performed for different reasons, so calorie requirements may vary from patient to patient.
in mathematics an inverse function is a function that reverses another function if the function f applied to an input x gives a result of y then applying its inverse function g to y gives the result x and vice versa i e f x y if and only if g y x
The General Logarithmic Functions. The natural logarithm function is defined as the inverse of the natural exponential function. So it's perfectly natural to define the general logarithmic function as the inverse of the general exponential function. Consider y = 2, the exponential function of base 2, as graphed in Fig. 5.1. Clearly it's one-to-one, and so has an inverse. This inverse is called the logarithmic function of base 2 or logarithm of base 2, and denoted log 2. Thus if y = 2 then x = log 2 y.
